Guys i been searching for months, i keep getting yelled at from the boss for playing on the internet too much so can i get some help. I switched directions from a emanage ultimate to just using a RRFPR.

Specs:
98 Forester 5mt
VF43
Perric FMIC w/ 2.5" piping
2.2 bottom end
2.5 heads
8:1 static compression
Walbro 255
3" turbo back
Tial 38mm ext. waste gate to dump
MTX-L Wideband


1) Anyone know the maximum flow rate for a 98 forester MAF before it volts out and trips a CEL.

2) Rather than using a 6:1 FMU with stock injectors, I would prefer to use a 4:1 with 440cc injectors, will the stock ecu run 440's Ok off boost?

Also my dash pod has a wideband gauge and a boost gauge. One more hole to fill, was thinking either fuel pressure or EGT, any suggestions?

I routinely hit 4.8/9 volts without popping a CEL.

I'll let someone else chime in on this.

I would go with either an EGT or an oil pressure gauge, both of these can save your engine.
